Ghost

Ghost - Alan Lightman Despite its title, the book is not about the supernatural. Being written by a theoretical physicist, it dabbles more in quantum mechanics -- and even at that, not much, just a couple of experiments to determine if the event was imagined or conjured. In fact, there is only one or two lines about what was perceived to have been sighted. Throughout, it was merely referred as the protagonist having "seen something." There was a sense of anticipative build-up as the book advanced, but the "hurrah" did not materialize (pun not intended).
